Jan,
Too funny! Yoga or running clothes seem to be the style here, at least in the warm weather so you are right in fashion Jan. After all is said and done, when you are cutting your bones in your driveway, you need to wear comfy clothes, not fancy ones!
My yoga teacher wears her yoga clothes all the time too. I only wear mine when I have a class and then usually for the rest of that day. Now that the weather will get colder, its back to shoes and socks and sweaters and slacks. Maybe some of the smaller sizes I have will fit now. It will feel like a whole new wardrobe to me.
I'm sure that Key West is even more casual, so why would you even think of wearing city-slicker type clothes?
